Mechanism of Action
Bacitracin: Inhibits bacterial cell wall synthesis, by preventing the incorporation of amino acids and nucleotides into the cell wall
Lidocaine: Topical anesthetics that reversibly block nerve conduction near their site of administration, thereby producing temporary loss of sensation in a limited area
Absorption
Bacitracin: Not substantially absorbed from intact or denuded skin, wounds, or mucous membranes
Lidocaine: Skin and mucosal absorption is highly variable; most anesthetic agents exist as solids and are only superficially absorbed through intact skin
